The company is a subsidiary of Israel Aerospace Industries. Some 200 companies vied for the tenders, which will provide a $300,000 to $500,000 grant to develop a model. The tender was announced late last week.

In total, eight companies are building prototypes for the nearly 200,000-mile-long wall. Four will be concrete and four will have see-through or “smart” walls. Elta was chosen to work on the see-through walls project.

Elta manufactures radar systems and components for branches of the American military. It also provides radar components for the Israeli military, which purchases them using U.S. military aid, which must be spent in the United States. At its Israeli headquarters, Elta manufactures radar systems for Arrow missiles, the Iron Dome anti-missile system, espionage and fighter jets, according to Ynet.
